setcontext() and setcontext() on ARM processor

[John (Eljay) Love-Jensen]

Hi Ranjith,

Is your operating system POSIX.1-2001 compliant, or Single Unix Specification version 2 (from 1997) compliant?

Those are the standards which specify setcontext, getcontext, makecontext, and swapcontext.  (If I'm not mistaken.  Knock on wood.)

If your operating system does not conform to POSIX.1-2001 or SUSv2 (or later), then your operating system's Standard C Library need not provide them.

If provided, they would be declared in the <ucontext.h> header.

HTH,
